HTTP Error 404
HTTP Error 404 received when subscribing huge number of Documents. This is not related to eB limitation or any setting from eB side. This limitation is from IIS (Internet Information Services). See below how to avoid it.
To change this limitation open IIS Manager, select your site and double click on Request Filtering
Open 'Edit Request Filtering Settings' menu by pressing 'Edit Feature Settings' from Request Filtering Action bar (RQ.jpg), and in this menu increate 'Maximum query string (Bytes)' to 6000. If you still get this error try to increase to 10k. After applying this setting you might need to restart IIS.
